GAR-COUPLING.

Specification of Letters Patent.

Patented Dec. 23,1919.

Application filed. March as, 1919. Serial No. 285,930.

To all whom it may concern:

Be it known that f, ARTHUR E. MONABB, a subject of the King of England, and resident of Monessen, in the county of lWestnioreland and State of Pennsylvania, have invented a new and useful Improvement in Car-Couplings; and I do hereby declare the following to be a full, clear, and exact description thereof.

My invention relates to car-couplings and more particularly to an automatic link-coupler adapted for use in connection with ingot cars and charging buggies in steel plants, although I do not wish to limit its use to any particular type of car, as it may be found applicable to any type of railroad car.

The object of my invention is to provide a simple and efficient form of coupler by means of which the automatic coupling of the cars is quickly and positively effected, and in which the parts are so constructed and arranged as to be strong and durable and not liable to get out of order.

To these ends my invention comprises the novel features hereinafter set forth? and claimed.

In the accompanying drawing, Figure 1 is a longitudinal sectional view of my improved coupler showing portions of cars in act of coupling; Fig. 2 is a like view showing the cars coupled and the position of the coupling being shown in dotted lines when released; and Fig. 3 is a sectlon on the line 3-3, Fig. 2.

In the drawing 1 have illustrated my invention as applied to an ordinary form of ingot car for use in steel plants, and the numeral 2 designates portions of such cars provided with the wheels 3. The drawhead 4: has the flanges 5 which fit down into the seats or recesses 6 formed in the frame 7 of the car, and said frame has the projecting portion 8 on which said drawhead rests for support.

The drawhead i has the flaring opening 9 leading into the pocket 10. A hook portion or projection 11 is formed within the drawhead 4:, said hook portion having the outer inclined face 12 and the inwardly projecting nose 13. The frame of the car is slotted at 1st for the insertion of the link-lifter 15, said link-lifter having the crank portions 16 and 17 at opposite ends thereof. This link-lifter is inserted through the slots 14- and is then moved down into the offset 18 which forms a bearing for said link-lifter and in which it is adapted to be rocked. The link-lifter has the lifting-arm 19 which extends through an opening 20 in the drawhead l into the pocket 10 in position to lift the coupling-link 21 to disengage it from the hook 11 as will more fully hereinafter appear.

The drawhead 22 is likewise provided with flanges 23 which fit into seats 2-1 in the frame of the car, and said coupler has the down wardly extending hook-portion or projection 25 within the pockets 26. This llOOlI-POltlOIl 25 has the downwardly and inwardly inclined face 27. Projecting up in front of the pocket 26 so as to form the passage 28 between the hook-portion 25 tion 29 which forms a support for the web 30, supporting the coupling-link between its openings 31 and 32.

The link 21 is connected to the drawhead 22 by inserting the link into the pocket 26 through the passage 28 whereupon the end of the link so inserted is raised until the hook-portion25 of the drawhead enters the opening 32 of the link. The web-portion 30 of said link rests upon the projection 29. In this manner the link is connected to the draw-head and normally rests in the horizontal position, as indicated in dotted lines Fig. 1. When, however, it is desired to couple the cars, the car bearing the drawhead 1- is brought up in position, and as said cars move toward each other the free end of the link 21 will ride up the inclined face 12 of the hook-portion 11 until said hook portion registers with the opening 31 whereupon said link will drop of its own weight down into position to engage the hook as shown in F '2, there being sufficient play to allow the link to pass over the nose 13. When in this position the coupling link acts to couple the cars securely together, and there is practically no liability of the cars becoming uncoupled, due to jerking or jolting as the nose 13 will prevent the accidental disengagement of the link from the hook-portion 11. Furthermore, the link cannot become accidentally disengaged from the hook 25. When it is desired to uncouple the cars the operator from either side of the operating device operates one of the cranks 16 or 17 which rocks the link-lifter so that the arm 19 engages the link and lifts it to disengage it from the hook-portion 11 of the drawheacl 4-.

By my invention I provide a very simple and efficient form of automatic link-coupler is the projec-- in which the cars when once coupled are held securely in position. against accidental uncoupling, and the linkwhen uncoupled is so connected to one of the cars as to preclude its becoming disconnected therefrom and lost. Furthermore the linkis normally sup ends, a second drawhead, and an upwardly extending hook-portion on said second drawhead adapted to be engaged by said link.

2. In a car coupler, the combination of a draw-head, a downwardly extending hook- ,portion on saiddrawhead, a link engaging said hook-portion, a web portion on said link intermediate its ends, a support on said drawhead upon which the said web rests, a second drawhead, and an upwardly extending hook-portion onsaid second drawhead adapted tobe engaged by said link,

3. In a car coupler, the combination of a drawhead, a downwardly extending hookportion on said draw-head, a link engaging said hook-portion, means on said drawhead for supporting said link intermediate its length normally in a horizontal position, a second drawhead, and an upwardly extend.- inghook-portionon said second drawhead adapted to engaged by said link.

l. In a car coupler, the combination of a draw-head, a downwardly extending hookportion on said drawhead, a link engaging said hook-portion, means on said drawhead for supporting said link intermediate its length normally in a horizontal position, 2.

second drawhead, an upwardly extending hook-portion on said second drawhead having a downwardly and outwardly inclined face whereby said link travels up said face to engage said upwardly extending hook portion.

5. In a car coupler, the combination of a drawhead, a ClOWHWHICll Y extending hookportion on said drawhead, a link engaging said hook-portion, a web on said link intermediate its ends, a support on said drawhead forming a rest for said web, a second drawhead, an upwardly extending hookportion in said second drawhead adapted to be engaged by said link, and a linklifter in said second drawhead.

6. In a car coupler, the combination of a drawhead, a downwardly extending hookportion on said draw-head, a link engaging saidhook-portion, a cross-web on said link, a support on said drawhead on which said cross-web rests, a second drawhead, an upwardly extending hook-portion on said second drawhead adapted to engage said link, and a nose on said. last mentioned hookportion.

7. In a car coupler, the combination of a drawhead, a downwardly extending hookportion on said drawhead, a link adapted to engage said hook-portion, a cross-web on said link, a support on said drawhead upon which said cross-web rests, a second drawhead, an upwardly extending hook-portion on said second drawhcad adapted to be en gaged by said link, a rock-shaft, and an arm on said rock-shaft entering said second draw-head inposition when raised to engage said link whereby it may be disengaged from said upr xardly extending hook-portion.

In testimony whereof, I the said Anrnun E. MGNABB have hereunto set my hand.
